Melt spinning device

ABSTRACT

A melt spinning device produces a plurality of multi-filament threads which includes a spinning apparatus, a cooling apparatus, a drawing apparatus and a winding apparatus. The drawing apparatus has a plurality of godet units entwined by threads, each of said units having a plurality of godets, which are axially rectified to a coil spindle of the winding device. The transition of the threads as yarn from the drawing device to the winding device is executed by a guide godet which is aligned axially crosswise to the godets of the godet units and under the drawing device, so that the threads can be guided by simple partial wrapping after rotation of the thread running plane of the yarn by 90°.

The invention relates to a melt spinning apparatus for the production of multiple multifilament yarns in accordance with the preamble of claim 1.

A melt spinning device of the stated type is known from WO 2004/074155.

For the production of synthetic yarns, such melt spinning apparatuses are combined in a multiple number, to form a complete spinning facility in a machine hall. In this connection, a high level of space utilization is desired. The greater the number of installed melt spinning apparatuses, the higher the production output of the spinning facility. Aside from the machine pitches of the melt spinning apparatuses, productivity is determined, to a significant extent, by the number of yarns that can be produced per melt spinning apparatus. In this regard, there is a desire to configure melt spinning apparatuses as compact as possible, with the greatest possible number of yarns.

In the case of a melt spinning apparatus of the stated type, a spinning device, a cooling device, a drawing device and a windup device are disposed one below the other, to produce a vertical yarn run. Because the spinning device with the spinnerets, the treatment device with the godet units, and the windup device with the winding locations require different distances, in each instance, between the yarns that are conducted in parallel, spreading the yarns apart or bringing them together is unavoidable. Within the yarn web, however, the aim is always to ensure that each of the multifilament yarns produced in the melt spinning apparatus has essentially the same properties. For this reason, deflections and spreads that lead to different yarn tensions in the multifilament yarns should be avoided, if at all possible. In the case of the melt spinning device of the stated type, a deflection device as well as a vertically oriented guide roller are therefore used in the transfer of the yarns from the treatment device to the winding locations of the windup device, in order to obtain the most compact yarn guidance possible, by means of multiple deflections. Such yarn guides, however, also lead to undesirable yarn tensions building up. Deflection on stationary deflection means, in particular, causes increased yarn friction.

From WO 2004/015137 A1, a further melt spinning apparatus is known, in which the godets of the treatment device are oriented to lie transverse to a spool spindle of the windup device, for pulling the yarns off and drawing them, in order to configure the windup device and the treatment device as compact as possible. In this connection, however, godets around which the yarn passes only once are preferred in the drawing device, on order to remain within the machine pitch defined by the windup device. In the case of godets that project a long distance, on which the yarn web is guided with multiple encircling loops, the godets can therefore hardly be combined with the windup device to form a structural unit. For the production of fully drawn yarns with greater yarn titers, however, godets around with the yarns are looped multiple times are absolutely necessary for yarn guidance and to build up the drawing forces.

It is now the task of the invention to further develop the melt spinning apparatus of the type mentioned initially in such a manner that the yarns drawn on godet units around which they are looped multiple times can be passed to the winding locations in a manner that is as gentle as possible on the yarns, without spreading.

A further goal of the invention lies in making available a melt spinning apparatus of the stated type with which fully drawn yarns (FDY) can be produced parallel, next to one another, in the greatest possible number.

This task is accomplished, according to the invention, in that the guide godet is oriented axially transverse to the godets of the godet unit, underneath the drawing device, in such a manner that during the transition, the yarns can be guided on the guide godet with a single partial loop around it, after rotation of the yarn run plane of the yarn web by 90°.

Advantageous further developments of the invention are defined by the characteristics and combinations of characteristics of the dependent claims.

The invention is characterized in that the components that significantly influence the depth of the melt spinning apparatus are directed in the same direction, so that a machine depth essentially predetermined by the winding device is utilized to place the godet units of the drawing device. The yarn web can be passed directly to the guide godet that is oriented transverse to the godets of the godet unit the drawing device, by means of a rotation of the yarn run plane of the yarn web, without any deflection and spreading. Rotation of the yarn web takes place, out of the yarn run plane determined by the drawing device, by an angle in the range of 90°, into a new yarn run plane defined by the guide godet. Here, the yarn run plane is understood to be the plane spanned by the yarns that are guided parallel next to one another. In this way, spreading of the yarn web for distribution of the yarns onto the winding locations is minimized. The required deflection can be implemented solely by means of rotating deflection means such as the guide godet.

In a first further development of the invention, feed of the drawn yarns to the winding locations of the spool-up machine can be performed with a single partial loop of the yarn web on the guide godet. For this purpose, the guide godet is disposed above the spool spindle, on the side, next to the winding locations, so that after the yarns run off the guide godet, they can be distributed onto the individual winding locations.

Alternatively, however, the possibility exists of assigning a second guide godet, directed in the same direction, to the guide godet above the spool spindle, which second godet is disposed on the side, next to the winding locations. In this way, a winding tension for winding the yarns up in the winding locations can be influenced, particularly by means of the drive of the guide godets.

Furthermore, the possibility exists of utilizing the guide segment formed between the guide godets for further treatment of the yarns. Thus, it is provided, according to a further development of the invention, that a swirling device is disposed between the two guide godets.

In order to be able to produce a plurality of yarns at the same time, the further development of the invention in which the windup device is formed by two spool-up apparatuses disposed next to one another, which each have multiple winding locations, has proven itself. For this purpose, the guide godet is preferably held in the center, above the spool-up apparatuses. In this way, the depth of the windup device, in particular, can be kept low at a large number of yarns. For improved yarn guidance, the spool-up apparatuses are preferably structured with mirror symmetry relative to one another, so that the distribution of the yarn web after running off the guide godet can take place from a plane of symmetry.

The distribution and feed of the yarns to the winding locations preferably takes place according to the further development of the invention in which multiple deflection rolls that are disposed directly ahead of a changing device, in each instance, in the winding locations, are provided between the guide godet and the winding locations. In this way, the yarns can be passed to the winding locations with low yarn friction.

For yarn stability in the guidance of the yarns as a yarn web, the melt spinning apparatus according to the invention can be further improved in that a guide means that brings about a change in the yarn run plane of the yarn web about an angle in the range of 90° is provided between the guide godet and the last godet of the drawing device. In this way, the run of the yarn web off the last godet of the drawing device and the run of the yarns of the yarn web onto the guide godet can be significantly stabilized.

In order to be able to obtain the greatest possible number of yarns within the machine pitch caused by the spinnerets, the further development of the invention in which the spinnerets are structured as a double spinneret, in each instance, is particularly preferred, by means of which two multifilament yarns can be extruded per spinneret. In this way, a great number of yarns can be produced within the spinning device, at a very compact arrangement of the spinnerets in parallel. Thus, the possibility exists that the row of spinnerets are oriented transverse to the axes of the godet units of the drawing device and form a machine operation side, together with the free ends of the godet units and the free end of the spool spindle of the windup device. To stabilize the yarn runs, a guide means is provided between the spinnerets and the drawing device, by means of which a change in the yarn run plane by an angle in the range of 90° is brought about.

In order to be able to cool each of the individually extruded multifilament yarns uniformly in spite of the compact construction of the spinning device, the further development in which the cooling device has multiple cooling cylinders each having a gas-permeable cylinder wall, which cylinders are disposed within a blowing chamber, is particularly advantageous. In this way, each of the yarns of the yarn web can be cooled under essentially the same conditions.

In the configuration of the spinnerets as a double spinneret, the further development in which each of the spinnerets has a cooling cylinder assigned to it, where the cooling cylinders are divided into two separate cooling zones, is particularly preferably used. In this way, multiple yarns can be extruded and cooled at the same time per spinneret and cooling cylinder.

The melt spinning apparatus according to the invention is particularly suitable for producing fully drawn yarns (FDY).

In the following, the invention will be described in greater detail using some exemplary embodiments of the melt spinning apparatus.

The figures show:

FIG. 1 schematically, a side view of a first exemplary embodiment of the melt spinning apparatus according to the invention, FIG. 2 schematically, a front view of the exemplary embodiment from FIG. 1, FIG. 3 schematically, a side view of a further exemplary embodiment of the melt spinning apparatus according to the invention,

FIG. 4 schematically, a front view of a further exemplary embodiment of the melt spinning apparatus according to the invention.

In FIGS. 1 and 2, a first exemplary embodiment of the melt spinning apparatus according to the invention is shown schematically in multiple views. FIG. 1 shows the exemplary embodiment in a side view, and in FIG. 2, the exemplary embodiment is shown in a front view. Unless an explicit reference is made to one of the figures, the following description applies to both figures.

The exemplary embodiment has a spinning device 1, a cooling device 3, a drawing device 4, and a windup device 22, which are disposed one underneath the other, in order to obtain a yarn run that is essentially directed vertically.

The spinning device 1 has a spinning bar 9 that carries multiple spinnerets 2 on its underside.

As is evident from the representation in FIG. 2, two spinnerets 2 are held on the spinning bar, which are configured, respectively, as a double spinneret 8.1 and 8.2. Each of the double spinnerets 8.1 and 8.2 held on the spinning bar 9 is coupled, in each instance, with a multiple pump 6, by way of separate melt lines. The multiple pump 6 is preferably configured as a planetary gear pump, where two separate sets of planetary gears are assigned to each double spinneret 8.1 and 8.2. The multiple pump 6 is driven by way of a pump drive 7. In this connection, feed of a polymer melt takes place by means of a melt intake 5 that is coupled with the multiple pump 6.

The cooling device 3 is provided underneath the spinning device 1; it has a blowing chamber 10 that is connected with an air conditioning device, not shown here. Multiple cooling cylinders 11.1 and 11.2 that are assigned to the spinnerets 2 are disposed within the blowing chamber 10. The cooling cylinders 11.1 and 11.2 each have a gas-permeable cylinder wall, so that a cooling medium introduced into the blowing chamber 10 penetrates uniformly into the interior of the cooling cylinders 11.1 and 11.2.

As is particularly evident from the representation in FIG. 2, each of the cooling cylinders 11.1 and 11.2 has a partition wall 12 in the central region, by means of which two separate cooling zones are formed in the cooling cylinder 11.1 and 11.2. Thus, a filament bundle extruded by one of the double spinnerets 8.1 and 8.2 can be introduced into each of the cooling zones.

The configuration of the blowing chamber 10 and of the cooling cylinders 11.1 and 11.2 is shown as an example. Fundamentally, the possibility also exists of forming the blowing chamber 10 by means of an upper and a lower chamber, which are connected with one another by way of a perforated metal sheet. In this connection, a cooling cylinder penetrates through both chambers of the blowing chamber; this cylinder has a gas-permeable wall in the upper chamber and a closed wall in the lower chamber. The connection with the air conditioning device then takes place by way of the lower chamber of the blowing chamber.

Alternatively, however, the possibility also exists of forming the cooling cylinders 11.1 and 11.2 by means of a blowing wall oriented transverse to the spinnerets 2, so that a cooling air stream that is directed transversely can be produced.

As is evident from the representations in FIG. 1 and FIG. 2, the cooling cylinders 11.1 and 11.2 open into a cooling shaft 13, in which the yarns are guided for cooling.

Because each of the extruded multifilament yarns is formed by a plurality of filament strands, bringing together the filaments per yarn takes place at the outlet of the cooling device 3. For this purpose, multiple collecting yarn guides 14 and a preparation device 15 are provided. In this exemplary embodiment, the preparation device 15 is shown as a roller preparation, as an example. Fundamentally, however, pin preparations can also be used in this connection.

For pulling off and drawing the extruded yarns as a yarn web, the drawing device 4 follows the cooling device 3. In this exemplary embodiment, the drawing device 4 has two godet units 16.1 and 16.2. The godet units 16.1 and 16.2 are configured identically and consist, in this exemplary embodiment, of a driven godet 17 and a companion roll 18 that is mounted so as to rotate. The godet 17 is driven by a godet drive 31. The yarns are guided on the godet units 16.1 and 16.2 as a yarn web 33, with multiple loops around them. In this connection, a differential speed is set between the godets 17 of the godet units 16.1 and 16.2, in order to draw the yarns of the yarn web 33.

In the transition from the cooling device 3 to the drawing device 4, a first rotation of the yarn run plane by 90° is required, because the yarn run plane spanned by the spinnerets runs offset relative to the yarn run plane formed by the godet units 16.1 and 16.2. In this connection, the plane in which the yarns of the yarn web 33 are guided next to one another is referred to as the yarn run plane.

To transfer the yarn web, a guide means 19, by which the yarn web is rotated and, at the same time, the yarns are brought together at a treatment distance from one another, is provided between the preparation device 15 and the first godet 17 of the godet unit 16.1 of the drawing device 4.

As is evident from the two representations of the first exemplary embodiment, a guide godet 20.1 follows the drawing device 4. The guide godet 20.1 follows the last godet 17 of the godet unit 16.2, in order to pull the yarn web 33 off the godet unit 16.2. For this purpose, the guide godet 20.1 is oriented axially transverse to the godet 17 of the godet unit 16.2, so that during the transition, the yarns can be guided on the guide godet with a single partial loop, by means of a rotation of the yarn run plane by 90°.

The guide godet 20.1 is held on a godet support 34 that supports itself on a machine frame 30 of the windup device 22. A godet drive 31 assigned to the guide godet 20.1 is held on the opposite side of the godet support 34.

As is evident from the representation in FIG. 1, the guide godet 20.1 has a second guide godet 20.2 assigned to it, which is disposed on the godet support 34, on the side, next to multiple winding locations 23.1 to 23.4 of the windup device 22. A swirling device 21 is provided between the guide godets 20.1 and 20.2; the yarns of the yarn web 33 can be treated separately from one another by means of this device.

The windup device 22 has multiple winding locations 23.1 to 23.4, in which the yarns of the yarn web 33 are wound up to form a spool 26, in each instance. The winding locations 23.1 to 23.4 are configured identically and each have a deflection roll 27 and a changing unit 28. In this connection, the spools 23 are simultaneously wound on a spool spindle 24.1 or 24.2, which are held projecting out of a spool turret 25 and are alternately guided into an operational region and a changing region. To place the yarns of the yarn web 33 onto the respective spools 26, a press-down roller 29 is provided, which lies against the circumference of the spools 26. The spool turret 25 and the press-down roller 29 are held in the machine frame 30 in movable manner.

The drives of the windup device 22 are not shown here, because such windup devices, also referred to as spool turrets in the industry, are sufficiently known. In this connection, the godet drives 31 of the guide godet 20.1 and 20.2, which are jointly supplied with electricity and jointly controlled, advantageously form a control unit.

In the exemplary embodiment shown in FIGS. 1 and 2, the yarn run of the yarn web 33 is shown in the drawing for an explanation of the method of functioning. In this connection, a plurality of fine filament strands is extruded by the two double spinnerets 8.1 and 8.2, from a polymer melt; these strands, after cooling, are brought together to produce a total of four multifilament yarns, by means of bringing them together and preparing them. Fundamentally, the possibility exists that in addition to preparation, pre-swirling of the filaments also takes place, in order to produce yarn consolidation that is required for treatment of the yarns.

Subsequently, the yarn web 33 formed by the four yarns is drawn off the spinnerets 2 by means of the first godet 17 of the godet unit 16.1, where the yarn web 33 is transferred from a first yarn run plane that is spanned through the row of the spinnerets 2 to a yarn run plane that is offset by 90°. The second yarn run plane is determined by the axial orientation of the godets 17 of the godet units 16.1 and 16.2, transverse to the row of the spinnerets 2.

In the drawing device 4, the yarn web 33 is drawn by means of differential speeds of the godet units 16.1 and 16.2. In this connection, the godets 17 of the godet units 16.1 and 16.2 are advantageously structured in heated manner.

At this point, it should be explicitly mentioned that the configuration of the godet units 16.1 and 1.62 is only an example. Fundamentally, the godet units 16.1 and 16.2 can alternatively also be formed by two driven godets that have heated guide mantles. Furthermore, multiple godet units could also be used, which optionally consist of godets having a companion roll, or of multiple godets, or of individual godets.

After drawing of the yarn web 33, the yarn web 33 is pulled off by means of the guide godet 20.1 that follows the drawing device 4. In this connection, the yarn web is guided out of the yarn run plane spanned for treatment and transferred to a guide plane rotated by 90°, which is determined by the axial orientation of the guide godet 20.1, where the guide godet 20.1 is oriented essentially transverse to the godets 17 of the godet units 16.1 and 16.2. The yarn segment between the godet unit 16.2 and the guide godet 20.1 can advantageously be utilized for shrink treatment, where the guide godet 20.1 is driven independent of the guide unit 16.2. Furthermore, the possibility exists that the guide godet 20.1 is structured to be heated.

For further treatment, the yarn web 33 is passed to the swirling device 21, which is held between the guide godets 20.1 and 20.2. In this connection, advantageous yarn tensions for swirling the yarns of the yarn web 33 can be adjusted by means of different circumference speeds of the guide godets 20.1 and 20.2. For this purpose, the guide godet 20.2 is driven by a godet drive 31, so that furthermore, an independent windup tension can be produced on the yarns of the yarn web.

At the end, the yarns of the yarn web 33 are distributed onto the individual winding locations 23.1 and 23.4 and wound up to form a spool 26, in each instance. Because of the equal treatment by means of multiple gentle deflections by means of rotating deflection means, each yarn of the yarn web 33 has essentially the same characteristics, so that the spools can be produced with essentially identical windup tensions.

The number of yarns that are extruded, drawn, and wound up at the same time, as selected in the exemplary embodiment according to FIGS. 1 and 2, is only an example. Fundamentally, usually more than four yarns per melt spinning apparatus are produced in a spinning facility. However, the number of yarns is not important for the explanation of the invention.

In FIG. 3, a further variant of the melt spinning apparatus according to the invention is shown schematically in a side view. The exemplary embodiment is essentially identical with the exemplary embodiment according to FIG. 1, so that only the differences will be explained at this point, and for the remainder, reference is made to the above description.

In the exemplary embodiment of the apparatus according to the invention shown in FIG. 3, a guide means 32 and a guide godet 20 are disposed between the drawing device 4 and the windup device 22, for guiding the yarn web 33. The guide godet 20 is held on the godet support 14, on the side, next to the winding locations 23.1 and 23.4, so that the yarns of the yarn web 33, which are guided on the guide godet 20 with a partial loop around it, can be fed directly to the winding locations 23.1 to 23.4.

In order to rotate the yarns of the yarn web by 90° after they run off from the godet unit 16.2, in the yarn run plane, the guide means 32 is provided, so that the off run of the yarn web at the godet unit 16.2 and the on run of the yarn web on the guide godet 20 can be stabilized using the guide means 32. In this connection, rotation of the yarn web 33 takes place without deflection and spreading, in a straight yarn run.

The function of the exemplary embodiment shown in FIG. 3 is identical to the function of the exemplary embodiment according to FIGS. 1 and 2, so that at this point, reference is made to the above description and no further explanation will be given.

The deflection means for transfer of the yarn web from the drawing device to the windup device, shown in FIG. 3, can advantageously also be integrated into the exemplary embodiment according to FIG. 1 Likewise, the possibility exists of structuring the exemplary embodiment of the melt spinning apparatus shown in FIG. 3 without an additional guide means.

In FIG. 4, a further exemplary embodiment of the melt spinning apparatus according to the invention is shown schematically, in a front view. The exemplary embodiment is essentially identical with the above exemplary embodiment according to FIG. 3, so that in order to avoid repetition, only the differences will be explained, and for the remainder, reference is made to the above description.

In the case of the exemplary embodiment shown in FIG. 4, the windup device 22 is formed by two spool-up apparatuses 35.1 and 35.2 disposed next to one another. The spool-up apparatuses 35.1 and 35.2 are arranged with mirror symmetry relative to one another, and both possess the same structure. Each of the spool-up apparatuses 35.1 and 35.2 therefore has multiple winding locations 23.1 to 23.4. The windup device shown in FIG. 3 therefore represents the side view of one of the spool-up apparatuses 35.1 and 35.2. In this regard, reference is made to the description given for FIG. 3.

The spool-up apparatuses 35.1 and 35.2 are operated synchronously, in order to wind the yarns of the yarn web 33 up to form spools, in each instance. The yarn web 33 is passed in by way of a guide godet 20 that precedes the windup device 22. For this purpose, the guide godet 20 is held in the center of the two spool-up apparatuses 35.1 and 35.2, on a support frame 37 above the spool-up apparatuses 35.1 and 35.2. The guide godet 20 is disposed to project out of the godet support 34 and driven by way of an electric motor.

After the yarns of the yarn web 33 run off the guide godet 20, the yarn web is divided, so that each spool-up apparatus 35.1 and 35.2 winds up the same number of yarns to form spools.

A drawing device 4 is disposed on the support frame 37, above the spool-up apparatuses 35.1 and 35.2. In this exemplary embodiment, the drawing device 4 is also formed by two godet units 16.1 and 16.2, which each have two driven godets 17. The godets 17 of the godet units 16.1 and 16.2 are preferably operated as godet duos, so that a differential speeds for drawing the yarns can be set between the godet units 16.1 and 16.2.

The godets 17 of the godet units 16.1 and 16.2 are oriented with their axes to be the same as the spool spindles 24.1 and 24.2 of the two spool-up apparatuses 35.1 and 35.2. In contrast, the guide godet 20 disposed between the godet unit 16.1 and the windup apparatus 22 is directed transversely, so that during the transition of the yarns from the godet unit 16.2 to the guide godet 20, the yarn web is rotated by an angle in the range of 90° in its yarn run plane. In this connection, no further guide means is provided between the godet unit 16.2 and the guide godet 20.

In this exemplary embodiment, the godet units 16.1 and 16.2 are disposed in godet boxes 36.1 and 36.2, respectively. Thus, heated godets 17 are preferably used in the godet units 16.1 and 16.2, so that a thermally insulated environment for treatment of the yarns is formed within the godet boxes 36.1 and 36.2.

The spinning device 1 and the cooling device 3 are configured identical with the exemplary embodiment according to FIGS. 1 and 2, but the number of spinnerets is doubled. Thus, a total of four double spinnerets 8.1 to 8.4 is provided, in order to extrude two yarns simultaneously per spinneret location. For a further explanation, reference is made at this point to the above description of FIG. 2.

In the exemplary embodiment according to FIG. 4, the spinnerets are also oriented in a row-shaped arrangement, which runs transverse to the godet axes of the godets 17. In this regard, the yarns of the yarn web 33 are transferred from a spinning plane determined by the spinnerets to a treatment plane determined by the godet units 16.1 and 16.2. In this connection, a guide means 19 is provided, in order to rotate the yarn run plane of the yarn web by an angle in the range of 90°. The guide means 19 is disposed directly ahead of the drawing device 4. In this connection, the yarns are jointly guided parallel next to one another, as a yarn web.

A collecting yarn guide 14 and a preparation device 15 are disposed between the drawing device 4 and the spinning device 1, in order to bring the filament strands that are extruded per spinneret together into yarns.

The exemplary embodiment shown in FIG. 4 represents a particularly compact arrangement for the production of a plurality of yarns within a spinning location. The function of the exemplary embodiment shown in FIG. 4 is identical with the function of the exemplary embodiments mentioned above, so that no further explanation will be given in this regard.

The exemplary embodiments shown in FIGS. 1 to 4 are examples of the structure and placement of the drawing device. Fundamentally, the possibility exists of integrating additional treatment steps and treatment assemblies in the region between the spinning device and the windup device.
